large-cupped daffodil

Large-cupped daffodils, such as Narcissus 'Chromacolor', require regular watering to maintain a healthy bloom. Water newly planted bulbs immediately after planting and then weekly during the growing season until the foliage turns yellow. Aim to keep the soil moist but not waterlogged. During the peak flowering season reduce watering slightly but ensure the soil does not completely dry out. Reducing watering gradually after flowering will help the plant to build up energy for its next bloom cycle. As a general guide, give the plant an inch of water per week, either from rainfall or irrigation.

Large-cupped daffodil (Narcissus 'Chromacolor') needs about 6 - 8 hours of sunlight a day during the early stages of growth. As the seasons change and the winters come, these daffodils can also benefit from full, direct sunlight up to 8 hours a day. While direct sunlight is preferable, they can tolerate light shade in the summer months, with no more than 4 hours of direct sunlight a day.

Large-cupped daffodil (Narcissus 'Chromacolor') should be pruned lightly in the late spring after the flowers have dropped off. The foliage should be trimmed back 1-2 inches above the soil level to promote regrowth. Pruning should be done when foliage yellows off in the warmer days of summer, as this indicates that the daffodil has finished its growth cycle for that season. Deadheading spent blooms should also be done to help promote additional bloom the following spring. Pruning should be done with sharp, clean blades to reduce the risk of disease and fungus.
